This option prevents the library from sending PING frame with ACK flag set automatically when PING frame without ACK flag set is received. If this option is set to nonzero, the library won’t send PING frame with ACK flag set in the response for incoming PING frame. The application can send PING frame with ACK flag set using nghttp2_submit_ping() with :enum:NGHTTP2_FLAG_ACK as flags parameter.
